wholly of some of these materials, at a minimum feed cost, and ex- 

 pensive standard feeds thus saved for the producing herd or flock. 

 The materials referred to as partial substitutes for common feed- 

 ing stuffs are straw from small grains, rice, or leguminous crops, 

 stalks of Indian corn or grain sorghums, grain and rice stubble, sugar- 

 beet tops and leaves, cannery refuse, by-products from the orchard 

 or truck gardening, etc. The average chemical composition of these 

 materials for which analyses are available, with estimated digestible 

 components, will be seen from the following table. For the sake of 

 comparison, this also includes corresponding figures for alfalfa hay 

 and barley.
